How to represent Linear Functions?

A linear function is one that is formed when a variable y varies directly with a variable x. That is, when y increases, x also increases and the opposite is also true.

The equation y = 3x - 5 represents a function.  This statement is said to be true because every value of x gives a different value of y and as such we can say it maps different elements to different images.

A function can only be represented by a straight line on the coordinate plane.  This statement is false because a function can also be represented by a circle, ellipse, parabola, etc.

Question 3 (2 points)
What translation takes the graph of f(x) = 4x - 3 to the graph of g(x) = 4x - 6 ?
Translation of 3 units down
Translation of 6 units left
Translation of 6 units down
Translation of 3 units right

Answers

Answer: The graph of g(x) = 4x - 6 is a translation of the graph of f(x) = 4x - 3.

A translation of a function results in a shift of the graph of the function, either horizontally (left or right) or vertically (up or down).

When the graph of a function is shifted down, the y-coordinates of all the points on the graph decrease. When it's shifted to the left, the x-coordinates of all the points on the graph decrease.

In this case, the graph of g(x) = 4x - 6 is a vertical translation of 3 units down from the graph of f(x) = 4x - 3.

The y-coordinates of all the points on the graph of g(x) = 4x - 6 are 3 units less than the y-coordinates of the corresponding points on the graph of f(x) = 4x - 3.

Therefore, the correct answer is:

Translation of 3 units down.

Answers

The approximate percentage of total pay that fringe benefits make up is 10%

The term called percentage in math is defined as a number or ratio that can be expressed as a fraction of 100

Here we have to find the approximate percentage of total pay that fringe benefits make up.

As the total compensation offered to the workers or employees by employers in different countries can usually be bifurcated into two broad components.

Here we have to know that the first one is based on wages & salaries components and the second one is the fringe benefits component.

Here this one includes the benefits components usually consist of supplementary benefits such as gratuity, pension contribution, transportation service, accommodation facility, etc.

Here as per the report published by the Bureau of Labor Statistics, U.S. Department of Labor in 2020 said that the approximate of the total pay that the fringe benefits make up usually range from 26.1% - 37.3%.

Based on that the percentage of fringe benefits could vary from the type of industry such as the goods-producing industry or service-providing industry.

So, the increased percentage is calculated as

=> 37.3 - 26.1

=> 11.2

Therefore, the correct option is (b).

How the future value is determined?

The future value can be determined by using the FV table or formula.

We can also ascertain the future value using an online finance calculator as follows:

Zahra's Investment:

N (# of periods) = 11 years

I/Y (Interest per year) = 8.625%

PV (Present Value) = $8,800

PMT (Periodic Payment) = $0

Results:

Future Value (FV) = $21,863.03

Total Interest = $13,063.03

Christopher's Investment:

N (# of periods) = 4015 days (11 years x 365)

I/Y (Interest per year) = 8.25%

PV (Present Value) = $8,800

PMT (Periodic Payment) = $0

Results:

Future Value (FV) = $21,805.22

Total Interest = $13,005.22

Future Values:

Zahra's = $21,863.03

Christopher's = $21,805.22

Difference = $57.81 ($21,863.03 - $21,805.22)

Three-dimensional space is quantified by volume. It is frequently measured quantitatively with SI-derived units (such the cubic metre and litre) or with a variety of imperial or US-standard units (such as the gallon, quart, cubic inch). Volume and height are related in how they are defined (cubed). The volume of a container is typically thought of as its capacity, or the amount of fluid (gas or liquid) that it could hold, as opposed to the amount of space the container occupies. Utilizing naturally occurring containers of a comparable shape and subsequently, standardized containers, volume is measured. Arithmetic formulas make it simple to determine the volume of some basic three-dimensional shapes.

Can you give an example of a number for the empty cell of the table that would give the United States the comparative advantage in the production of airplanes? What about South Korea?

b. What exact number would you have to place in the empty cell of the table for it to be impossible that trade between the United States and South Korea could benefit both

Answers

The number for an empty cell would be 20 so any number below this benefit South Korea and above this benefit the United States. This also makes it impossible for trade between these two countries.

If a country can manufacture a significant number of goods with the same resources as another country, it has an absolute advantage. If a country can manufacture a certain commodity more cheaply and with higher quality than another country, it has a comparative advantage.

In the given scenario, 1000÷10=100 autos are sacrificed by the United States to manufacture one airplane which is the opportunity cost. In comparison to the United States, South Korea requires twice (2000÷1000) as long to construct an airplane.

a) The number of hours for South Korea to produce one auto would be 2×10=20. Because of this, South Korea would benefit from any number below 20, while the US would benefit from any number above 20.

b) The empty cell value would be 20 for South Korea to have the same opportunity cost as the United States. So mutually beneficial trade cannot exist without comparative advantage.

Speed = Distance × Time

Speed = 3. 6 x 104 miles per hour

Time = 1 hour

3. 6 x 104 = Distance × 1

Distance = 374.4 miles

The distance to be covered 7. 2 x 108 miles
